‡Suction tested to ASTM F558 at the cleaner head, dust-loaded against upright market.

*Suction testing based on ASTM F558, dust-loaded against robot market.

1Historically, manufacturers based “no loss of suction” claims on a single test that can be completed before a vacuum’s bin is full. We repeat that test to bin full 100s of times consecutively, amounting to 10 years’ worth of test dust, to ensure vacuums containing Dyson Cinetic™ science maintain constant suction.

4Calculated using PE International GaBi software and method developed with Carbon Trust based on 5 years use and dry times measured using Dyson test method 769 based on NSF P335 with a measurement of 0.1g residual moisture.

5Suction tested to ASTM F558 at the cleaner head, dust-loaded. Lightweight market defined by machines weighing less than 14.55 lbs.

6Usage based on 2 paper towels per dry (data from Dyson internal research –Sept 2008). Calculations include standby power. Cost based on average paper towel cost of $0.01 and an electricity charge of $0.10 per kWh (source: US Department of Energy). Paper towel dispenser, warm air hand dryer, and Dyson Airblade™ hand dryer purchase costs are excluded from comparison. Dry times calculated using Dyson test method 769 based on NSF protocol P335 using a measurement of 0.1g residual moisture.

♦♦Assumes up to 6% savings in air conditioning costs for every degree Fahrenheit that thermostat is raised. (See U.S. EPA and D.O.E. Energy Savings Calculator). Also assumes elevated air speed may offset increase in air temperature by up to five degrees (See ASHRAE Standard 55-2004-Thermal Environmental Conditions for Human Occupancy). Air multiplier must be used in conjunction with and in close proximity to air conditioning ventilation output in each room to recognize savings benefit. Actual savings may vary based on use and other factors.

***Calculated lifetime based on LED L70.

****Based on Tolomeo lettura halo aluminium reading lamp using a 70W halogen bulb at a cost of $3.55 electricity cost of $0.15 per kWh and 144,000 hours duration.

o Dyson received the highest numerical score among canister and stick vacuums in the J.D. Power 2017 Vacuum Satisfaction Study, based on 6,965 total responses and measures the opinions of consumers who purchased a canister or stick vacuum in the previous 12 months surveyed February-March 2017.
